Do you want to refuel the oil-free silent air compressor

Oil-free silent air compressor, as the name suggests, is an air compressor designed to do not need to use lubricating oil during operation. This type of air compressor usually uses special design and materials to reduce the friction and wear between mechanical parts, so as to achieve oil-free operation.

The water-lubricated oil-free variable frequency screw air compressor of Shanghai Grankering Group is such a device. It uses water lubrication technology, through water to replace the traditional lubricating oil, to achieve the oil-free compression. This design not only avoids the risk of oil contamination, but also provides more pure compressed air.

Question: Since it is an oil-free air compressor, does it not need to add any lubricant at all in daily use?

Answer: Yes, the oil-free silent air compressor does not need to add any lubricant during normal operation. Its design concept is to reduce maintenance costs and avoid oil pollution through oil-free technology. It should be noted, however, that while the oil-free compressor itself does not require refueling, other auxiliary systems (such as certain types of bearings or seals) may still require a small amount of lubrication or cooling. In these cases, a lubrication system completely isolated from the compressed air is usually used. However, for the water-lubricated oil-free variable frequency screw air compressor of Shanghai Granklin Group, due to its use of water lubrication technology, even these small amounts of lubrication requirements have been replaced by water. Therefore, in daily use, users do not need to worry about adding lubricant.
